Packages and Binaries:
This package contains integration scripts for configuring vlan interfaces via ifupdown (/etc/network/interfaces). For further details see vlan-interfaces(5) man page in this package.
Please note that these integration scripts only supports a limited set of interface naming schemes, which means you might be better off with writing your own ifupdown hooks using ip(route2) directly in /etc/network/interfaces rather than using this package.
It currently also ships a wrapper script for backwards compatibility called vconfig, that replaces the old deprecated vconfig program with translations to ip(route2) commands. This compatibility shim might be dropped in future releases, please use ip(route2) commands directly.
Your kernel needs vlan support for this to work, see “modinfo 8021q”.
How to install:
sudo apt install vlan
VLAN (802.1q) configuration program.
[email protected]:~# vconfig -h Usage: add [interface-name] [vlan_id] rem [vlan-name] set_flag [interface-name] [flag-num] [0 | 1] set_egress_map [vlan-name] [skb_priority] [vlan_qos] set_ingress_map [vlan-name] [skb_priority] [vlan_qos] set_name_type [name-type] * The [interface-name] is the name of the ethernet card that hosts the VLAN you are talking about. * The vlan_id is the identifier (0-4095) of the VLAN you are operating on. * skb_priority is the priority in the socket buffer (sk_buff). * vlan_qos is the 3 bit priority in the VLAN header * name-type: VLAN_PLUS_VID (vlan0005), VLAN_PLUS_VID_NO_PAD (vlan5), DEV_PLUS_VID (eth0.0005), DEV_PLUS_VID_NO_PAD (eth0.5) * FLAGS: 1 REORDER_HDR When this is set, the VLAN device will move the ethernet header around to make it look exactly like a real ethernet device. This may help programs such as DHCPd which read the raw ethernet packet and make assumptions about the location of bytes. If you don't need it, don't turn it on, because there will be at least a small performance degradation. Default is OFF.
